Substrate



FIG. 1 is a front perspective view of a substrate, according to a new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a front elevational view thereof;

FIG. 4 is a back elevational view thereof;

FIG. 5 is a right elevational view thereof;

FIG. 6 is a left elevational view thereof; and,

FIG. 7 is cross-sectional view of the substrate taken along line 7-7, as shown in FIG. 2 .

The broken lines on the substrate, compact, and drill bit in FIGS. 1-7 depict portions of the substrate, compact, and drill bit that form no part of the claimed design.

The appearance of any portion of the substrate between the break lines shown in FIGS. 1 and 3 through 7 forms no part of the claimed design.

The underside of the substrate (i.e., the side of the cutting tools opposite the side shown in FIG. 2 ) does not form part of the claim design.

The parallel “dash-dot” broken lines represent a symbolic break in the claimed design. Anything that appears in between, including the parallel “dash-dot” broken lines, forms no part of the claimed design. 

CLAIM The ornamental design for a substrate, as shown and described.
